Seek, the M22s plus a good sub(which you'll have) are excellent for music. One step that will get you an even better listening experience is to drop the concept of "strict" or "pure" 2-channel listening. Most of the sound at a concert reaches the listeners as reflected ambience from directions other than the front. This sound has to be mixed into the front channels because there's no place else to put it in 2-channel formats. HT receivers(such as your excellent 606)can apply processing such as DPLII to extract the ambience from the front channels and send it to the surrounds where it belongs, making the home listening experience a bit more realistic. I'd never voluntarily limit myself to listening through only front speakers when surrounds are available.

So, as a temporary measure you can use whatever speakers you have as side surrounds, although they won't precisely match the excellence of the M22s. When your budget permits, you should consider the QSs to further improve your listening. As far as amplification, you already have all you need for optimum sound quality.
